[LLVMdev] Using -view-legalize-dags

[Gaster, Benedict]

I'm trying to debug an issue in codegen but when using:

 

llc -view-legalize-dags -O1 -march=x86-64 -o c-01.s c-opt.bc

 

I get a .dot file and while it has the DAG the nodes do not have any
text. I'm probably doing something very stupid but I cannot figure what
it is can anyone point out what I'm doing wrong?

 

Thanks,

 

Ben
